Description

Technical Field

[0001] The utility model relates to the technical field of motor insulation detection, in particular to an automobile motor insulation detection device. Background Art

[0002] Motor insulation testing is a test method used to evaluate the insulation performance of a motor to ensure that there will be no insulation failure or electric shock hazard when the motor is running. This test can help determine whether the motor has sufficient insulation strength to prevent current from passing through the insulation material. A conventional motor insulation testing method commonly used is to use an insulation resistance tester for testing. The instrument will apply a certain DC voltage or AC voltage between the motor winding and the motor housing and measure the insulation resistance value. Depending on the type and specification of the motor, it is usually necessary to test a relatively high insulation resistance value. Regular motor insulation testing can help detect potential insulation problems early and take appropriate preventive measures to prevent motor failure or damage.

[0003] After searching, the Chinese patent announcement number is CN 220419401 U. The utility model discloses a DC power supply insulation detection device, which includes an adjustment box, and the two ends of the adjustment box are injection molded with clamping plates, and the bottom ends of the two clamping plates are slidably clamped with racks, and the same gear is meshed between the two racks. The gear is installed at the bottom end of the adjustment box through a rolling bearing plugged at the bottom end. The gear extends through the adjustment box through a rotating shaft welded on the top, and a knob is installed by welding. Slide blocks are welded on both sides of the ends of the two racks that are close to each other. The utility model controls the gear to mesh with the two racks by rotating the knob, and realizes the control of the two extension rods to move away from or close to each other, so as to increase the convenience of the detection range of the equipment.

[0004] The above patent still has some shortcomings: although the spacing of the detection contacts can be adjusted by meshing the racks on both sides of the gear, the mechanical structure occupies a large space. When opening the hood to detect the automobile motor, the inspector needs to hold the handle to explore the motor interface. The operating space is limited, which reduces the detection efficiency, and there are safety hazards when the inspector's body is inserted into the hood. Utility Model Content
